string(M)

string(M)
string -- access boot, configuration, or package string

Description

There are three string devices (the number in the first column is the string device's minor device number): 
 1  /dev/string/boot   read/write access to the bootstring
 2  /dev/string/pkg    read-only access to the package string
 3  /dev/string/cfg    read-only access to the configuration string
The bootstring (bootstring) is the string built by /boot from user input and from /etc/default/boot. The package string (pkgstring) lists what has been linked into the kernel at boot time. The configuration string (cfgstring) is a concatenation of all the output from printcfg(D3oddi).

The routines getbsvalue(D3oddi), getbsflag(D3oddi) and getbsword(D3oddi) provide an interface to /dev/string/boot and /dev/string/pkg. /dev/string/cfg can only be accessed directly.

Reading from the devices is non-blocking and non-destructive.
